Substrate Metal 776x243

Profiled Metal Substrates

Minimum 0.7mm galvanised steel. The minimum requirement to support the Monarplan membrane above the metal deck is insulation boards. In mechanically fixed roof build-ups, it is crucial to ensure that the rows of fasteners are installed in a perpendicular direction to the metal deck’s corrugations (or the single timber plank) in order to avoid a concentration of uplift forces on any one single element.

Aluminium decks shall be a minimum 0.9mm. For mechanically fastened systems, refer to Icopal’s Technical Department for confirmation of suitability of fastener.

Good roofing practice requires the roof to be free of significant ponding within 48 hours of rainfall. Where the structural deck does not provide drainage or removal of standing water within 48 hours, the substrate should be corrected to provide positive drainage.

It is recommended that all decks in a warm roof construction be sealed prior to installing the roofing system to prevent air infiltration beneath the membrane. Sealing the deck is accomplished by installing a vapour control layer over the deck and sealing around all penetrations.
